LPC11U6x is intended as a family of easy-to-use, USB-IF certified USB microcontrollers, with a more energy-efficient ARM Cortex-M0+ processor, significantly more flash and SRAM, more serial communications, a new 2-Msample/sec ADC and more versatile timers.
These additional features allow the LPC11U6x to tackle a wider range of applications in consumer, commercial and industrial markets such as metering and data collection, wired and wireless routing, handheld medical equipment, and PC/gaming accessories, among others.
The LPC11U6x family includes a USB device controller certified by the USB Implementers Forum (USB-IF) and gives designers access to USB software, tools and shortcuts. Embedding the USB drivers in ROM cuts design time and shrinks application program footprint while increasing reliability, while an on-chip PHY reduces the solution BOM and design complexity. NXP provides a royalty-free USB device driver stack, extensive example code for popular device classes, and a free PID/VID program which make USB development easy for designers with any level of USB expertise.
To support more demanding data and buffering requirements, as well as larger application code sizes, the LPC11U6x extends memory options by doubling flash to 256 kB and tripling SRAM to 36 kB. More rigorous I/O requirements are supported by expanded serial connectivity, including five USARTs, two I 2Cs, 2 SPIs, and up to 80 GPIOs, along with a 12-channel, 12-bit, 2-Msps ADC for higher bandwidth and higher-precision input. New to the LPC11Uxx Series, the LPC11U6x uses an ARM Cortex-M0+ core for power efficiency.
LPC11U6x MCUs also include both standard and configurable timers/PWMs for advanced timing requirements. Higher operating temperatures (up to 105 ºC) make them suitable for more industrial environments.
